Compound used to reduce or eliminate buildup of static electricity
"Antistatic" redirects here. For the Australian rock band, see Antistatic (band).
An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static electricity. Static charge may be generated by the triboelectric effect[1] or by a non-contact process using a high voltage power source. Static charge may be introduced on a surface as part of an in-mold label printing process.[2]
The role of an antistatic agent is to make the surface or the material itself slightly conductive, either by being conductive itself, or by absorbing moisture from the air; therefore, some humectants can be used. The molecules of an antistatic agent often have both hydrophilic and hydrophobic areas, similar to those of a surfactant; the hydrophobic side interacts with the surface of the material, while the hydrophilic side interacts with the air moisture and binds the water molecules.
Internal antistatic agents are designed to be mixed directly into the material, external antistatic agents are applied to the surface.
Common antistatic agents are based on long-chain aliphatic amines (optionally ethoxylated) and amides, quaternary ammonium salts (e.g., behentrimonium chloride or cocamidopropyl betaine), esters of phosphoric acid, polyethylene glycol esters, or polyols. Traditional migrating antistatic agents include long-chain alkyl phenols, ethoxylated amines, and glycerol esters, such as glycerol monostearate. Migrating antistatic agents offer cost-effective protection for short-term applications, but other applications need longer-term protection or the lower resistivity required to prevent sparks and protect electronics from electrostatic dissipation. These applications utilize permanent antistatic agents or conductive additives such as carbon black, conductive fibers, and nanomaterials.[3][4] An antistatic agent for the treatment for coatings may also involve an ionic liquid or a solution of a salt in an ionic liquid.[5] Indium tin oxide can be used as transparent antistatic coating of windows. It is also possible to use conductive polymers, like PEDOT:PSS and conducting polymer nanofibers, particularly polyaniline nanofibers. In general these systems are not very durable for coating, especially antimony tin oxide is used for durable systems, often in its nano form, it is then formulated to a final coating.
